A 9 sided nonagon has interior angles that add up to 1260 degrees
(2n - 4) x 90 = 1260 where n is the number of sides.ie 180n = 1260 + 360n = 1620/180 = 9Your polygon is a nonagon (or enneagon)
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1260 degrees
Suppose the polygon has n sides. Then (n - 2)*180 = 1260 So (n - 2) = 1260/180 = 7 and therefore, n = 7 + 2 = 9

A 9 sided nonagon has interior angles that add up to 1260 degrees
Well, darling, the angle sum of a polygon with 9 sides is 1260 degrees. Each interior angle of a regular nonagon measures 140 degrees. So, if you add up all those interior angles, you get 1260 degrees. Math doesn't have to be a drag, honey!
It is a regular 9 sided polygon whose 9 interior angles add up to 1260 degrees
9099 * * * * * The sum of the interior angles is (9 - 2)*180 = 1260 degrees.

The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1260 degrees
Suppose the polygon has n sides. Then (n - 2)*180 = 1260 So (n - 2) = 1260/180 = 7 and therefore, n = 7 + 2 = 9
(n-2)*180 = sum of interior angles of any polygon where n = number of sides. (9-2)*180 = 1260 degrees.
